China's air pollution leading to more erratic climate for US, say scientists

I hate this.  The title says one thing and the article says another.  Where they really lost me was when they talked about their "sophisticated climate models".

According to the team's findings, which were released on Monday in the Proceedings of the National Academy of Sciences, these changes could ultimately contribute to erratic weather in the US.

 We already know pollution from China is sending mercury over here.   Why isn't that good enough to know.  I guess it isn't scary enough!!
